liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

Fenton process, as one of the most conventional advanced oxidation processes, is widely used in the treatment of specific wastewaters, especially landfill leachate. In current study, the main target was to evaluate some neglected aspects of Fenton process in operational applications. Thus, three novel responses were introduced. Mass removal efficiency evaluates overall recalcitrant destruction ...

This study was performed with the aim of investigating the efficiency of the Nano photocatalytic of ultraviolet and titanium dioxide compound and rice husk silica adsorbent (UV/TiO2/RHS) in removal reactive red 198 dye from synthetic aqueous solutions. The removal of reactive red 198 dye was done in batch reactors with a volume of 250 ml using RHS deposited by titanium dioxide in the...

The methods presented in this work provide a potential tool for characterizing contaminant source zones in terms of mass flux. The problem was conceptualized by considering contaminant transport through a vertical "flux plane" located between a source zone and a downgradient region where contaminant concentrations were measured. The goal was to develop a robust method capable of providing a sta...

BACKGROUND AND PURPOSE Targeting the prostaglandin I2 prostanoid (IP) receptor to reduce stroke injury has been hindered by the lack of selective drugs. MRE-269 is the active metabolite of selexipag showing a high selectivity toward the IP receptor. Selexipag has been recently approved for clinical use in pulmonary hypertension. We hypothesized that postischemic treatment with MRE-269 provides ...

soil pollution has become one of the main concerns which because of containing chemical and hazardous materials, alerts the whole environment, and finding solutions to overcome this problem would be very important. many ways have been discovered and examined for soil treatment and one of the most applicable methods is soil washing. in this research, the effect of saponin biosurfactant in crude-...

Abstract Magnetic resonance elastography (MRE) is a technique to identify the viscoelastic moduli of biological tissues by solving the inverse problem from the displacement field of viscoelastic wave propagation in a tissue measured by MRI. Because finite element analysis (FEA) of MRE evaluates not only the viscoelastic model for a tissue but also the efficiency of the inversion algorithm, we d...
